Abstract

The invention relates to a method for producing 1,1' binaphthalenylidene-4,4'-diones of general formula (I), wherein R1 represents C1-6 alkyl, C1-6 alkoxy, phenyl, substituted phenyl, benzyl or benzyloxy; R2, R3, R4, and R5 independently of one another represent hydrogen, C1-6 alkyl, C1-6 alkoxy, phenyl, substituted phenyl, benzyl or benzyloxy. Production takes place by oxidative coupling of the corresponding naphthols in the presence of a peroxide and a precious metal catalyst.
